UPDATE
Issued at 719 PM EDT Mon Mar 18 2024
For the latest NE FL and SE GA Daily Key Messages please visit: https:// www.weather.gov/media/jax/briefings/nws-jax-briefing.pdf
High pressure will build from the northwest through the night, with a trend toward clear skies. Due to the gradient between the exiting front and building high, a surge of winds will move south across the region beginning this evening, and lasting through around sunrise.
The strongest winds will be along the coast.
Temperatures will fall off sharply Tonight, with lows ranging from the mid 30s over inland SE GA, to the lower 40s over coastal NE FL.
Frost is not expected due to the winds. However, wind chills values will drop below freezing across most inland areas.
SHORT TERM
(Tuesday through Wednesday night)
Issued at 203 PM EDT Mon Mar 18 2024
High pressure conditions will be in place through the middle of the week with dry weather, mostly clear skies, and predominantly mild winds persisting through Wednesday. There is a possibility for frost formation early Wednesday morning for some areas however conditions for development are borderline so confidence at this time is low. Coolest temperatures for the week will be on Tuesday with high temperatures in the lower to mid 60s on Tuesday and rising into the lower 70s Wednesday. Overnight low temperatures will similarly rise from out of the upper 30s up into the mid 40s Wednesday night going into early Thursday morning.
LONG TERM
(Thursday through next Monday)
Issued at 203 PM EDT Mon Mar 18 2024
The influence of high pressure will diminish and move off to the east on Thursday with chances for showers and thunderstorms increasing on Friday as instability associated with a low pressure system traveling across the Gulf of Mexico and then being followed by a dry front bringing high pressure conditions over the forecast area by the end of the weekend. Temperatures will drop to be slightly below the seasonal average by the end of the week but will return to normal levels by the end of the weekend.
AVIATION
(00Z TAFS)
Issued at 719 PM EDT Mon Mar 18 2024
Skies will clear Tonight, so VFR conditions will prevail this period. A surge of winds will move across the area this evening into the overnight, with the strongest winds along the coast. These gusty winds will diminish toward sunrise. Have used variable winds in the later period of this forecast, as the winds become fairly light.
MARINE
Issued at 203 PM EDT Mon Mar 18 2024
A cold front and wave of low pressure will continue to move across the area today with scattered to numerous showers through the afternoon and into the evening. In the wake of the cold front, a rapid increase in northwest to north winds is expected tonight and will support gale force conditions with a gale warning is now in effect. Winds will lighten Tuesday afternoon as high pressure to the west shifts over the waters. High pressure will be the dominant weather feature until the next weather disturbance arrives Thursday night which will increase winds and build seas again through Friday.
Rip Currents: Low risk today with low surf of about 1 foot.
Increased risk will be possible on Tuesday due to increased northerly winds.
